ANSWER THE QUESTION... What is the most cost efficient way to design this component? One of the most significant changes in the design was the increase of the leg size from 1.5 inch round tube stock to 2 inch round tube stock. A few unique load cases required a step up in the overall strength of the tripod leg system. In the studies at left, you can see a few of the numerous studies we went through. Originally, we felt that welding doublers in a few key locations would do the trick. However, we finally decided that stepping up the stock tube size was the most efficient decision since it didn’t require the added welding and post-weld heat treating steps. Also, the 2 inch stock size offered much greater structural rigidity than the preliminary 1.5 inch tube. The final added benefit was that it was much less expensive to manufacture. |
